1. Master and identify the basic knowledge of fake and shoddy products, and buy high -quality and standard oil seals.

2. During installation, if the surface roughness of the outside of the axis is low or defects such as rust spots, rust, and closer, it should be polished with fine sand or oil stones; apply clean engine oil or lubricating oil at the corresponding position of the oil seal lip or shaft diameter. The outer ring of the oil seal is coated with a sealing glue, wrapped the key slot on the shaft with a hard paper to avoid scratching the oil seal lip mouth, and the oil seal is used to rotate inward. Or squeeze the spring and fail; if the lip is edged, the spring falls off, and the oil seal is skewed, it must be removed and reinstated. It should be noted that when the axis diameter does not wear and the oil seal spring elasticity is sufficient, do not tighten the inner spring without authorization.

3. When the general working conditions on the mechanical oil seal are bad, the environmental temperature difference, the dust of the dust, and the frequent vibration of the machinery shall be checked, maintained, and maintained.

4. If the bearing diameter and bearing are severely worn; the aging rubber seal rubber or spring failure, etc., should be repaired and replaced in time.

5. Failure should be eliminated in time for components or assembly of abnormal fever; avoiding mechanical speed and overloading to prevent the temperature of oil sealing lips from rising, rubber aging, and early wear of lip mouth.

6. To check the oil level frequently, if the oil impurities are too much, the new motor oil should be completely replaced when there are alloy powder and metal iron chips. The oil sign and quality of the replacement must meet the requirements of the season. It is recommended to add a Matre super sealing agent & lubricant to the oil. It is an excellent gear box additive that can form an inert material thin film on the part. Life can also reduce the noise of the gear box. The use of this Matre super sealing lubricant will not cause pollution or deteriorate oil.
